The Legislatures of British India included legislative bodies in the presidencies and provinces of British India, the Imperial Legislative Council, the Chamber of Princes and the Central Legislative Assembly. The legislatures were created under Acts of Parliament of the United Kingdom. Initially serving as small advisory councils, the legislatures evolved into partially elected bodies, but were never elected through suffrage. Provincial legislatures saw boycotts during the period of dyarchy between 1919 and 1935. After reforms and elections in 1937, the largest parties in provincial legislatures formed governments headed by a prime minister. A few British Indian subjects were elected to the Parliament of the United Kingdom, which had superior powers than colonial legislatures. British Indian legislatures did not include Burma's legislative assembly after 1937, the State Council of Ceylon nor the legislative bodies of princely states.
